Storage room
Cable line into the house > Cable modem, Time Capsule, and MoCA. This room is the heart of house wifi network.

Upstairs bedroom
Cable outlet > MoCA box > TiVo Premiere

It works for the TiVo, but...sure would like to add a second Airport to the bedroom, extending the otherwise weak wifi signal to that part of the house.

Is that possible? Where/how do I add an Airport to the bedroom setup?

MoCA Box upstairs: Has EtherNet port, yes? If so is this currently connected to Premiere?

Airport express can be added (setup to extend current network) and connected to network via the EtherNet on MoCA box. If necessary add a small (3 or port) EtherNet switch directly to box so both Airport Express and Premiere can be connected.

Thanks, Michael!

So that I don't misunderstand, this is what you suggest:

• Ethernet port on the MoCA box > ethernet switch

...one switch port > TiVo
...one switch port > Airport

Basically, the switch acts like a splitter, right...? Can't believe it's so simple (she says, feeling like a dork).

I just did this exact thing less than two weeks ago. (New house was too big for the router's Wi-Fi signal to reach, so I needed an extender.) There's a second port on an Airport Express to connect the Premiere to if you wanted to avoid the switch. Of course, that only works if the Premiere is the only thing in that area (besides the new Airport Express) that needs Ethernet. In my setup, I have a switch as well to support Blu-Ray players, etc.

Ohmygosh...this has been here under my nose the entire time.

Just passed the internet signal (via ethernet cables) from the MoCA, through the Airport Extreme, to TiVo. Am getting full wifi in the entire east end of the house now, plus TiVo is happy.

Additional note which just struck me: if the Premiere is 4 tuner model - you can enable MoCa in the Network Settings screen and remove the ethernet connection. All will come through the coax. This is where MoCA really shines.
